Is cornstarch OK to use on dogs?

Cornstarch is a fine, powdery starch that is made from corn. It has a variety of uses, including as an ingredient in recipes, as a thickening agent, and even as a dry shampoo. Some pet owners may wonder if it’s safe to use cornstarch on their dogs, such as dusting it on their fur to absorb excess oils. Here’s what you need to know about using cornstarch on dogs.

Is Cornstarch Safe for Dogs?

Yes, cornstarch is generally considered safe for dogs. Here are some key points about the safety of cornstarch for canines:

  • Cornstarch is non-toxic to dogs. If ingested in small amounts, it should not cause any harm.
  • It can be used topically on a dog’s skin and coat. Cornstarch will not typically irritate a dog’s skin.
  • It’s an ingredient in some dog shampoos and dry shampoos.
  • Cornstarch has been used for years by dog show handlers and groomers to help absorb oils and make coats look fluffier.

However, like any product, cornstarch does have some risks and drawbacks when used on dogs:

  • It should not be inhaled. Inhaling large amounts of cornstarch could potentially cause breathing issues.
  • It could irritate open wounds or hot spots. Avoid applying to broken skin.
  • Some dogs may be allergic to corn. Monitor for signs of an allergic reaction.
  • It may dry out your dog’s skin if overused.

Overall, when used properly and in moderation, cornstarch is considered low-risk for use on dogs. Make sure not to rub it vigorously into your dog’s coat, which could cause them to inhale it. And monitor your dog for any signs of skin irritation or allergic reaction.

Benefits of Using Cornstarch on Dogs

Here are some of the reasons people use cornstarch on their canine companions:

  • Absorb oils and dirt: Rubbing a small amount of cornstarch into your dog’s coat can help absorb excess oils and dirt. This helps freshen up their coat in between baths.
  • Reduce shedding: By absorbing oils on the skin and coat, cornstarch may help loosely attached hairs stay in place instead of shedding.
  • Detangle: Work a pinch of cornstarch through knotted, matted fur to help separate and detangle the strands.
  • Clean face and paws: Gently rub a little cornstarch on your dog’s face and paws to absorb dirt and oils they picked up outside.
  • Dry bath: Sprinkling cornstarch throughout their coat then brushing it out gives your dog a dry shampoo effect.

Cornstarch is also used to make homemade dry dog shampoo. And some groomers use it to prep dogs for show to make their coats look full, clean, and matte.

How to Apply Cornstarch to Your Dog

If you want to use cornstarch on your dog, follow these tips:

  • Brush your dog’s coat thoroughly before applying.
  • Rub a small amount between your hands first to remove clumps.
  • Start with a pinch of cornstarch and work it into areas that need refreshing.
  • Avoid rubbing vigorously, which can cause your dog to inhale the powder.
  • Pay special attention to paws, belly, folds, and other areas prone to oils.
  • Always avoid your dog’s eyes, nose, mouth, wounds, and other sensitive areas.
  • Brush thoroughly after applying to distribute the cornstarch and remove any excess.

You can apply cornstarch as often as needed to freshen up your dog’s coat and skin. But limit use to a few times per week at most, as overuse can dry out your dog’s skin.

Risks and Safety Tips

While considered safe for most dogs, keep these precautions in mind when using cornstarch:

  • Monitor your dog for signs of skin irritation or allergic reaction, and discontinue use if any develop.
  • Avoid getting cornstarch in your dog’s eyes, nose, or mouth.
  • Do not vigorously rub it into your dog’s coat, as inhaling the powder poses a risk.
  • Never use in place of medical treatment for skin issues without consulting your veterinarian.
  • Store cornstarch out of reach of your dog to prevent accidental ingestion.

Cornstarch is not a nutritionally complete diet for dogs. While small amounts generally won’t harm your dog if ingested, avoid feeding large amounts. And keep cornstarch stored securely so your dog can’t get into it.

Dogs with corn allergies should avoid cornstarch, as it could trigger a reaction. If your dog has any known allergies or sensitivities, check with your vet before use.

Cornstarch vs. Talcum Powder

Some pet owners may wonder whether talcum powder can be used on dogs as a substitute for cornstarch. However, talcum powder is not recommended for use on dogs. Here’s how cornstarch and talcum powder differ when it comes to safety for dogs:

Cornstarch Talcum Powder
Considered safe for use on dogs Not recommended for use on dogs
Low risk of inhalation issues Pose risk of lung irritation if inhaled
Low toxicity if ingested Talc is minimally toxic but still not advised for ingestion
Not linked to cancer in dogs Talc may contain asbestos, which can cause cancer

Due to concerns over lung irritation and possible asbestos contamination, most vets recommend avoiding talcum powder on dogs. Cornstarch is widely considered the safer option for dogs.

Other Powders to Avoid on Dogs

In addition to talcum powder, some other powder products are also not safe for use on dogs. Steer clear of applying the following powders on your pooch:

  • Baby powder – Often contains talc and fragrances that may irritate dogs’ skin.
  • Foot powders – Often contain zinc oxide or other ingredients that may be unsafe if licked off.
  • Baking soda – Can alter dogs’ skin pH and cause irritation.
  • Dusting powders – Household dusting powders may contain toxic chemicals if ingested.
  • Cat litter – Clumping cat litter can cause blockages or even cement in dogs’ intestines if ingested.

For dry shampoo and coat freshening, opt for pure cornstarch without added fragrances, chemicals, or other ingredients. Or use a dog-formulated dry shampoo.

Homemade Dry Dog Shampoo with Cornstarch

You can make your own dry shampoo at home using just a few natural ingredients:

Ingredients

  • 2 cups cornstarch
  • 1 cup baking soda
  • 10 drops essential oil (optional), such as lavender, citrus, or mint

Directions

  1. Mix together all ingredients until well combined.
  2. To use, sprinkle a small amount throughout your dog’s coat.
  3. Massage gently into coat, avoiding eyes, ears, nose, and mouth.
  4. Let sit for 5-10 minutes.
  5. Brush thoroughly to remove powder.

Store any leftover powder in an airtight container. Shake before each use to combine. Use sparingly, a little goes a long way!

When to See a Vet

While occasional use of cornstarch is generally fine for most dogs, see your vet if your dog experiences any of the following:

  • Signs of skin allergy or irritation after use, like redness, scratching, licking, or chewing at the skin
  • Respiratory issues like coughing, wheezing, or difficulty breathing after exposure
  • Vomiting, diarrhea, loss of appetite, or other signs of illness after ingesting
  • Cornstarch gets in eyes, nose, or ears
  • Excessive itching, redness, or odor even after use
  • Hot spots, wounds, or signs of infection

Skin issues like itching, irritation, infections, and hot spots often have an underlying cause. See your veterinarian to identify and address the root of the problem.

Also seek emergency vet care right away if your dog shows any signs of respiratory distress or obstruction after inhaling or ingesting cornstarch.

Conclusion

Used properly and in moderation, cornstarch can be a safe way to freshen up your dog’s coat and skin between baths. Its absorbent properties help remove dirt, oil, and odors. Just be mindful not to overuse it, and keep it away from your dog’s face, eyes, nose, and any open wounds.

Monitor for signs of skin issues or breathing problems after use. And check with your vet before use if your dog has any known allergies. With some precautions and proper use, cornstarch can be a helpful tool for keeping your dog clean, fresh, and comfortable between bath times.
